They mentioned somewhere in the literature when I bought my '04 Ultra that the '04 FLHTCUI's were fitted with a 160mm rear tire. (I mean 150mm....oops.) I assume that the MU85B16 that you mention is a 150. I looked in my '04 Touring parts book and the latest fender number that they show has a dash 02A number on it. The swing arm and axle show a dash 02 part number. Assuming that they didn't change the rear fender or swing arm and axle in '03 a 160 should fit.

My guess is that it would work based on part numbers. Like everything else, though, you will never know until you try.

The front should work, IMHO. The fender looks the same all the way back to 1949.

I think the size of the rear belt was changed when HD went with that new size tire. I also seem to remember that Markcuda said somewhere that he put a MU85 on his 03 EG. The different in the width is .31. Probably can be done if the rubber piece on the belt guard at the bottom is trimmed.

RIght you are about the belt. It has a 2004 part number. (40024-04). So they may well have changed to a narrower belt in '04 to match the 150 tire in the rear.

Did you notice it's getting to be nightmare trying to keep up with all the changes from year to year? Ain't no more of the old days when a part from a 10-15 years ago would fit right on a new one. I guess it's good in a way as it's progress the majority of the time.

The sprocket, and belt are the only differences I know of. Someone asked in a later issue of American Iron about this, they said the frame was changed, but I have found no evidence of this. I've called Harley but have found no-one that can or will tell me all the differneces to accomodate the larger rear tire.

Beserker, just put the mu85 on my 03 E G, needed to trim the belt guard flap to clear, it would spin freely but was right on the tire.The belt is REAL close to the tire, have not rode it yet finishing other work.Gonna keep a close eye on it if it rubs at all I will yank it quick. let you know what happens.

its a no go on the mu85, just too close to belt, no room for tire flex.fits the 03 EG fine otherwise. the extra load cap and tread depth would have been nice but not worth springing for the narrow belt and pulleys.

Just a little tidbit...I put the MU on my 96 FXSTC. At first glance everything was fine. Very close to the belt but still about an 8th inch clearance. After riding for about 50 miles I noticed that the top run of the belt was touching. I have decided to live on the edge and ride it.
